Im about to purchase a Alpine CV-1004 headunit and the salesperson told me about the Alpine KCE-104V. Im not sure what the KCE-104V unit is for. I was told it will give me more inputs and outputs but is really worth the $300? I have 7 monitors in my car, camera and tv tuner and all are hooked upto the pioneer switcher. If I purchase the KCE-104V will I still need the switcher or will this unit do everything upfront on the CV-1004 headunit? What advantages would I have with the KCE-104V? I wouldn't mind purchasing it if it will let me switch my monitors from the headunit instead of the pioneer swticher. My monitors and DVD player are SAVV so will I be able to use the KCE-104 for switching my other monitors?iAny suggestions would be great, thanks.
